	Oxide Summary
		Oxides are characterized by a redistribution of electrons, in which the oxygen atoms have a net surplus of electrons and the other atoms a net lack.
		Oxides of metals occur as ionic compounds, or salts, which are solid at room temperature.
		The oxides of the chemical elements in their highest oxidation state are predictable and the chemical formula can be derived from the number of valence electrons for that element.

	Process for the preparation of an iron(III) oxide catalyst or absorbent - Patent 4459370
		The invention relates to a process for the preparation of an iron(III) oxide catalyst or absorbent, in which iron is precipitated from an iron salt solution by means of hydroxyl ions in the presence of a carrier, the carrier is dried and optionally calcined.
		As a rule, heat-stable substances, such as silicon dioxide, aluminum oxide or titanium oxide are used as carrier for the catalytically active particles of iron oxide or iron.
		The distribution of the iron oxide on a thermally stable carrier with a sufficiently large surface area is therefore an essential requirement for the use of iron oxide as an absorbent for hydrogen sulfide.

	Corrosion (Site not responding. Last check: )
		The problem with iron as well as many other metals is that the oxide formed by oxidation does not firmly adhere to the surface of the metal and flakes off easily causing "pitting".
		(It should be noted, however, that certain metals such as aluminum, form a very tough oxide coating which strongly bonds to the surface of the metal preventing the surface from further exposure to oxygen and corrosion).

	[No title] (Site not responding. Last check: )
		X-ray diffraction analysis confirmed that the iron(III) oxide in the prepared Fe-Si adsorbents was amorphous, largely due to the retardation of the iron oxide crystallization by the presence of silicate species.
		These forms of iron(III) oxides retain their strong affinities to As(V) and As(III), but are limited to reactor configurations incorporating large sedimentation and filtration units, which cause difficulty in solid/liquid separation [18].
		Since the crystallization of iron oxides, for instance, the transformation of ferrihydrite to goethite, is strongly retarded by the presence of silicate species [20-23], the FeOOH formed through co-precipitation with silicate should be in an amorphous (or poorly crystalline) form.

		Generally, thermite is made by mixing Iron Oxide and Aluminum powder and igniting it at very high temperatures (a few thousand degrees).
		Although Copper Oxide thermite is probably the most common of the exotic thermites, one could also use other metal Oxides such as Tin Oxide, Lead Oxide, or any other metal Oxide which could be reacted with a reducing metal (such as Aluminum or Magnesium).
		Unless the thermite is sufficiently mixed, it may be difficult to ignite or sustain the thermite reaction.
